When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: Combination Figure 1-3This embodiment discloses a liquid dispensing device for food testing, including a base 1 and a cover 2 that are detachably connected. Specifically, the outer contour of the base 1 and the shell is a cylindrical shell structure, and the bottom of the shell is snapped onto the top of the base 1. During use, the shell is installed on the top of the base 1 as a covering structure. During maintenance, the shell can be easily disassembled to replace and clean the internal components.

[0027] A storage groove 11 is provided on the front side wall of the base 1. The storage groove 11 is close to the bottom. The storage groove 11 is a square sink structure in the front view. A horizontal storage platform 12 is provided at the bottom of the storage groove 11. The storage platform 12 is used to place a sample container. In this embodiment, the sample container is a sample cup 3. The sample cup 3 has an open top and scale lines on the side wall for accommodating food to be tested (especially liquid food).

[0028] A human-computer interaction module is also provided on the front side wall of the base 1. The human-computer interaction module specifically includes a display screen 13 and a button 14. The display screen 13 is used to display the working parameters and working status of the device, and the button 14 is used for parameter setting and function selection. The human-computer interaction module is electrically connected and controlled by the control chip. The control chip is arranged inside the base 1 and is used to receive corresponding signals and generate related instructions. Its physical structure is a circuit board. The electronic control module is flexibly designed and selected according to actual working requirements. It is an existing technology, and its specific structure and working principle are not repeated here. Those skilled in the art can select and implement it from the existing technology according to actual working conditions.

[0029] Combine Figure 2 A horizontal partition 15 is provided inside the base 1 . The partition 15 is located directly above the storage table 12 and is provided with a first opening 16 . The first opening 16 passes through the partition 15 longitudinally.

[0030] Furthermore, a horizontal turntable 5 is spaced apart above the partition 15. A vertical rotating shaft 41 is connected to the center of the bottom of the turntable 5. The rotating shaft 41 vertically passes through the partition 15 and is connected to a rotating drive member. The rotating shaft 41 is movably connected to the partition 15 (specifically, the rotating shaft 41 is connected to the partition 15 via a bearing). The rotating drive member is a rotating motor 4. A speed reduction steering gear is provided between the output end of the rotating motor 4 and the rotating shaft 41. The rotating motor 4 is fixedly connected to the base 1.

[0031] A plurality of barrels 6 are provided on the turntable 5 (in this embodiment, the number of barrels 6 is 6, which are arranged symmetrically with respect to the center of the turntable 5). The bottom of the barrel 6 is threadedly connected to the turntable 5 and can be easily disassembled during maintenance. The turntable 5 forms a second opening 51 that is compatible with the first opening 16 just below the inner area of ​​the barrel 6. When the barrel 6 is at the top threshold position of the storage slot 11, the second opening 51 is aligned with the second opening 51 to form a dropping path for the medicine in the feeding barrel 6 to fall into the sample cup 3 on the storage table 12.

[0032] Further, combined Figure 3 The barrel 6 is a straight cylindrical structure with upper and lower openings, and a support plate ( Figure 3 The middle tray (not labeled) is located at the bottom of the medicine bag 7 and has a through-hole for the output hose 71. The main body of the medicine bag 7 is placed on top of the tray, and the output hose 71 extends downward to the bottom of the tray. The peristaltic pump 8 is fixed to the bottom of the tray. It should be noted that the medicine bag 7 is a sealed bag structure. The possible use of liquid medicine is pre-packaged into the medicine bag 7. The peristaltic pump 8 is used to control the quantitative output of the medicine.

[0033] In order to make the discharging direction more stable and reliable, a nozzle 72 is provided at the output end of the output hose 71 , and the nozzle 72 is connected and fixed to the barrel 6 through a fixing frame 73 .

[0034] The display screen 13 , the button 14 , the rotary drive element and the peristaltic pump 8 are all electrically connected and controlled by the control chip.

[0035] During the specific implementation process, the rotating drive member can drive the turntable 5 to rotate. After rotating according to the threshold angle, it can control the barrel 6 at the threshold position to be transferred to the top of the storage table 12, so that its corresponding second opening 51 is aligned with the first opening 16 up and down, forming a blanking path. With the help of the peristaltic pump 8 working according to the threshold time, the output end of the output hose 71 can transport a fixed amount of medicine from top to bottom along the blanking path. This not only simplifies the liquid preparation steps in the food testing process, but also significantly improves the accuracy and efficiency of liquid preparation, which is of great significance to ensuring food safety.

[0036] Example 2: Based on Example 1, Figure 4 As shown, a counterweight 9 is provided on the top of the medicine bag 7 on the inner side of the barrel 6. The outer contour of the counterweight 9 is fitted with the inner contour of the barrel 6. The counterweight 9 can use its own gravity to press down the medicine bag 7. The counterweight 9 is made of aluminum alloy with a round cake structure, and the outer contour is polished into a smooth structure. During actual use, the size of the counterweight is selected according to actual needs. The purpose is to always provide an extrusion force on the medicine bag 7 so that the medicine in the medicine bag 7 is at the bottom as much as possible, so that the output of the medicine is more stable and reliable.

[0037] In other embodiments, a weighing module may be further configured on the storage table 12 to monitor the weight of the sample cup 3 and the weight difference before and after liquid preparation in real time, forming a feedback quality inspection mechanism to further improve the accuracy of liquid preparation.
